Title: Reception antenna with unwanted wave cut-off
Inventor: ODO KUNIHIRO
IPC: H01Q15/14
Filed: 1989-06-06
Abstract: PURPOSE:To prevent an unwanted wave received by arranging unwanted wave cut-offs at both sides of a receiving antenna. CONSTITUTION:The unwanted wave cut-off 2 is manufactured by bending a wire made of iron in wave shape. The pitch and the height of the wave are fitted in the pitch of the waveguide of the receiving antenna 3, and the height of it is also fitted in the pitch of the waveguide. The unwanted wave cut-offs 2 manufactured in such way are mounted at both sides of the UHF television antenna 3. It is enough to mount the cut-offs at only both sides of the receiving antenna 3, and distance between them is taken a little wider than the width of the receiving antenna 3. By using an antenna 1 comprised in such way, the unwanted wave can be cut off with the unwanted wave cut-off 2, which prevents it from being received, however, a wave targeted to be received can be received with the receiving antenna 3 passing between two unwanted wave cut-offs 2. Therefore, the irregularities on a picture due to the unwanted wave, etc., can be suppressed.

Abstract: PURPOSE:To prevent the flowing of concd. molten steel in the cast slab existing in a continuous caster and improve the segregation by decreasing the casting velocity to a specific velocity on and after completing the pouring into a mold in a light rolling reduction in the continuous casting method. CONSTITUTION:In the light rolling reduction in the continuous casting method, by producing the shortage of the molten steel static pressure on the after completing the pouring into the mold in comparison with the stationary state, the flowing of the concd. molten steel in the reverse direction to the casting direction is caused. By decreasing the drawing velocity by the quantity restraining the flowing of the concd. molten steel, the deterioration of segregation can be prevented. On and after completing the pouring into the mold, by decreasing the casting velocity at lower than that in the stationary state by 1-20%, the drawing is executed. For example, in the continuous caster for producing the slab having 300mm thickness and 500mm width, the high carbon steel cast at 0.90m/min the casting velocity in the stationary state is made to be drawn by decreasing to 0.85m/min the casting velocity on and after completing the pouring into the mold. By this method, the flowing of the molten steel can be restrained and a high segregation level is obtd.

Title: Cache memory control system
Inventor: EJIRI MASAHARU
IPC: G06F12/08
Filed: 1990-06-04
Abstract: PURPOSE:To make throughput maximum at the limit value of engineering by making the frequency of transfer in a memory bus minimum when the ratio of time for traveling an on-line processing program exceeds the limit value of engineering. CONSTITUTION:The cache is fixed when a software detects that the load of a transaction reaches the limit value. Then, bus competition with an MBUS 6 is decreased and the value of an OCCUP 3 is made lower than the limit value of engineering. At such a time, an MM 7 stores the value of the OCCUP 3 and the contents of the cache and a cache directory, and afterwards, a mode is set to enable reloading only once. Each time the miss hit of the cache occurs, it is compared with the lowest value of the OCCUP 3 in the past and when the value in this time is lower than the value, the MM 7 stores the value and the contents of the cache. Then, the optimum contents of the cache are realized by repeating this processing until the cache contents optimum for the transaction processing in the state of the engineering limit value are formed on the MM 7.

Title: Method and apparatus for automatic gain control of digital radio transmission system in space difference and/or angle difference
Inventor: ADERIO KONTEI
IPC: H04B7/02
Filed: 1993-05-25
Abstract: PURPOSE: To provide an inexpensive system by detecting two received signals and comparing two detected voltages and driving an amplification level in accordance with the result by a single signal having the maximum reception power. CONSTITUTION: Two variable gain devices arranged in two RF parts in front of the mixers 3 and 4, namely, RF amplifiers 1 and 2 are controlled by the control voltage of an automatic gain controller 7. The voltage of the device 7 detects a maximum power level at the input. In this case, the AGC voltage which drives both of amplifiers 1 and 2 measures the power of a divergent channel (D channel) by a detector 6 if an incoming signal which has power with respect to the D channel exists on a main channel. Thus, a signal is prevented from reaching a mixer with power higher than an input nominal level, and amplifiers 1 and 2 have the same gain in a band.

The reel rotates and reciprocates with the wire 1 being held by the pawl 4, and the wire 1 is automatically connected to the reel 6. And, after the completion of the connection of the wire 1 to the reel 6, the pawl 4 is released, and the wire 1 is uniformly wound on the reel by the rotation and reciprocating motion of the reel.

Title: Toner and fixing method for toner with electron beam
Inventor: SAITO JUNICHI
IPC: G03G15/20
Filed: 1992-05-14
Abstract: PURPOSE:To provide a toner having high offset resistance and durability by using a specified toner core material and a specified toner shell material. CONSTITUTION:This toner is a capsule-type toner having a toner core material and a toner shell material. The toner core material contains an electron-curing resin, while the toner shell material contains a thermoplastic resin having 40-110 deg.C glass transition temp. The toner core material in the toner has a part not cured with 50-99% gel fraction and has a three-dimensional net structure. Thereby, the inner cohesive force of the toner is hardly defeated by the adhesive force between a fixing roll and the toner, which raises the temp. for hot offset. Therefore, temp. difference between the cold offset and hot offset is increased so that the offset resistance is increased. When this toner is used for a copy machine, the developer in the developing zone 14 contains 5 pts.wt. of this toner and 95 pts.wt. of carrier. In an electron beam fixing machine 22, a nonscanning type electron beam irradiating machine with 200eV output can be used.
